Hereditary hyperferritinemia-cataract syndrome is an autosomal dominant genetic disorder that is characterized by high serum ferritin levels without iron overload and early-onset cataracts. The authors describe the case of a 26-year-old woman with hyperferritinemia (1153.3 ng/mL, reference range 11.0 - 306.8 ng/mL), with no other abnormalities in iron metabolism, associated with cataracts diagnosed at the age of three. The diagnosis was confirmed by genetic testing with detection of a heterozygous variant in the FTL gene (c.-168G>T). It is important to recognise hereditary hyperferritinemia-cataract syndrome to avoid unnecessary medical procedures.
